Spider-Slayer XIII
A biological-looking robot created by Alistair's assistant Max Young, the Mark XIII was a remake of one of Mendel Stromm's old Amoeboid robot and attacked Spider-Man while he and the Black Cat were battling the Scorpion. The Mark XIII ensnared Spider-Man in its tentacles and began to suffocate him. It was only when the Scorpion accidentally impaled the Slayer with his electrically-charged stinger that it was destroyed. The feedback from his attack left the Scorpion unconscious as well.
The Mark XIII was later rebuilt by Alistair as a member of his Spider-Slayer army, which was taken down by Spider-Man.
The Mark XIII was capable of stretching its body to extreme lengths and could also entrap enemies within itself, suffocating them. Its body was also extremely malleable, allowing it to twist and warp its shape.
